:. .ZClaiins. (01.120-426) nvetion' relates to a color-applying tool forapply;

ing precious metalpigment colors, such as those embodyfgold, silver andthe like, to ceramic and other surfaces.

j'var'ious types of color-applying tools for. applying Accordingly, anobject of the present'invention is'to provide a newand improvedcolor-applying tool which is so is constructed and arranged that itmaybe readily employed, forapplying precious metal pigment colors,

1 such :asthose embodying gold, silver, and the like, to

ceramic and other work surfaces while, at the same time,

enabling the parts of the new color-applying tool to be readily manuallyadjusted toprevent leakage or flow of the pigment colorwhen the tool is.not in use.

Another object of the present'inventionis to provide in itheinewcolor-applying .toola novel 'manually controlled .valve arrangementwhich is so designed-and construetedthatthe. partsof thenewcolor-applying tool may be readily manually adjusted to preventleakage or flow o f the pigment color when the 'tool is not in use.Other I and further objects will appear hereinafter';

nib portions 17-18"formed therein at its lower l e nd.

These nib portions 17-18 are slightly separated" from each other, as at20, and the lower end portions 17-18 thereof {are unthreaded and projectoutwardly'of the open end reduced lower end portion of the tip of "theshown in Figs. 1, 2 and 3. ,The externally threaded lower end and nibportion'17 of the rod-handle member fl-lz is threadedly engaged with theinternally, threaded lower end; portion 14-15 of th elcombinationreservoir and tip member 13-14-15. j

A valve seat is formed in the reduced lower end portion, 15 of thecombination reservoir and tip member 13-14,

' by providing an annular shoulder 21on the inner surface thereof, andthe'rod and handle 11-12 has a shoulder 22 formed thereonQimmediatelyabove the internally Fig. 6 is a central sectional view illustrating amodification of the invention; and a Fig. 7 is an exploded sectionalview illustrating the parts embodied in the modified form of theinvention illustrated in Fig. 6.

A preferred form of the present invention is illustrated in Figs. 1 to5, inclusive, of the drawings, where it is generally indicated at 10,and includes a manually operable cylindrical combination rod and handlemember 11 threaded nib portion 17, and this shoulder 22 is engage: ablewith the valve seat 21. i

. In the use of the'form oftheinvention shown in Figs; 1 to 5,inclusive, the combination color-receiving reser: I voirand tip member13 may be filled with precious metal" pigment color, such as colorsembodying gold, silver, or other precious metal pigments, forapplication to. eramiclsurfaces, and the like, and when so filledthe"rodand handle member 11-12 will be initially, posi? tioned so that theannular shoulder 22 thereonengages the valve seat 21 and thus preventsflow of the color] from the reservoir 13 into the passage 20 between thenib poiftions'17 "-1 8 when the worn not jn use.

However, when it desired to. usethe newicolor applying to'ol, as'shownin Figs. 'lto 5; inclusive, 'the rod aridharidle "rnember '11'1'12 n1aybe retractedyupwardlyi by manuallyjfrotating the same so as to raise theannular" shoulder 22 above the valve j'se'at 21, whereupon 'colorfwillflow from the body of the combination reservoir and tip memberli'rjdo'wn through the lower end portion 14-15;

thereof into thespace 20 between the nib portions 17-18 and'thence ontothesurface of a ceramicmaterial'or other work. Q

It will thus be noted that when th ing the valve seat 21, and when theparts are so arranged, leakage of the color will be prevented, thusovercoming a difiiculty experienced in the use of the prior artcolorapplying tools.

7 In the form of the invention illustrated in Figs. 6 and 7 of thedrawings those parts which are similar to corresponding parts oftheinvention illustrated in Figs. 1 to 5, inclusive, of thedrawings,'have been given similar reference numerals followed by theadditional and distinguishing reference character a.

The form of the invention illustrated in Figs. 6 and 7 of the drawingsincludes a relatively small storage receptacle 26 for precious metalpigment colors, such as those embodying gold, silver and the like. Thisstorage receptacle 26 has a frusto-conical shaped upper end portion 27,having an open upper end, and an externally threaded reduced lower endportion 28 which has a central passage 29'formed therein communicatingwith the interior 30 of the frusto-conical shaped upper end portion 27.

The form of the invention illustrated in Figs. 6 and 7 of the drawingsalso includes an internally threaded main coupling member 31, which hasan internally threaded frusto-conical shaped passage 32 formed therein,and this form of the invention also includes an auxiliary couplingmember or adapter 33.

The auxiliary coupling member or adapter 33 is externally threaded, asat 34, and has an internally threaded central passage 35 of reduceddiameter, formed in its upper end portion, and a relatively wider andunthreaded' central lower internal passage 36 formed therein.

7 e'fne'e color applying" is nqti guse t m y be r g in" upright postion. iii'a' suitable support, "with the'annular shoulder 22 engagcoupling member 31 for guiding the color-applying tool over the work,such as a ceramic surface 43, as is well understood in the art.

In the use of the form of the invention illustrated in Figs. 6 and 7 ofthe drawings the parts may be assembled as shown. This is accomplishedby inserting the combination reservoir and tip member 13'a--14a15ainto'the lower end portion of the frusto c onical. shaped central centralpassage 32 of the main coupling member 31, in which it will rest asshown in Fig. 6, with the gasket 37 resting on the upper end wall 39 ofthe tip member 13a14a--15a. The auxiliary coupling member 33'may then besecured in the threaded upper portion of the central passage 32 in themain coupling member 31 and the threaded lower end portion 28 of thereservoir or receptacle 26 then threadedly inserted into the threadedpassage 35 in the auxiliary coupling member 33.

The rod and handle member 11a may then be inserted through the centralpassage 3035363l} in the parts 263337 with the nib portions 17a--18athreaded into the threaded lower end portion 19a of the combinationreservoir and tip member 13a and with the shoulder 22a thereon engagingthe valve seat 21a. The color may then be poured into the reservoir 26through the open upper end thereof, whereupon it will flow by gravitydown through the central passage 302935--36-38 into the upper portion ofthe reservoir 13a in which it will be retained by the engagement of theannular shoulder 22a on the rod-handle member with the valve seat 21a.

When it is desired to use the new color-applying tool shown in Figs. 6and 7 the plunger rod and handle member 11a may be manually rotated toretract the annular ings, that the present invention provides a new andimproved color applying tool having the desirable advantages andcharacteristics, and accomplishing its intended objects, including thosehereinbefore pointed out, and others which are inherent in theinvention.

I claim:

1. A color-applying tool. especially adapted for applying precious metalpigment colors to ceramics and other shoulder 2211 from the valve seat21a, whereupon the color will flow from the upper portion of thereservoir 13a past the valve seat 21a and thence between the nibs.

17a-1'8a onto the work.

It will thus be seen from the foregoing description,

work surfaces and comprising a generally hollow frustoconical shapedcombination color reservoir and tip member including an apical portionhaving a tapered internally threaded bore formed therethrough and havingan annular shoulder formed therein on its inner surface inwardly of saidinternally threaded bore and providing a valve seat, a manually operablerod and handle member extending through said combination color reservoirand tip member and having a bifurcated externally threaded outer endportion providing a pair of nib portions threaded into the saidinternally threaded bore, each of said nib portions including an endportion extending;

from the outer end of the bore, said rod and handle member having anannular shoulder formed thereoninwardly of said externally threadedouter end portion thereof and said annular shoulder being adapted to betremovably engaged with said valve seat by manual rota-v tion of said rodand handle member so as to control flow of color from said combinationcolor reservoir and tip member into said bore and between and onto saidnib and tip member remote from said apical portion being open to receivecolors to be applied.

2. A color applying tool as defined in claim 1, in whichv each of saidnib portions has an unthreaded outer end portion normally extendingoutwardly beyond the apical portion of said combination color reservoirand tip member.
